Piage Czoski, an undergraduate at New Mexico Tech (NMT) and 2011 IRIS Intern, is just back from conducting research for her senior thesis in Antarctica. She arrived to Mc Murdo Station in late November and spent much of her time working on Mt. Erebus. Mt. Erebus ( 3,794 m in elevation) is the southern most active volcano located on Ross Island. Mt. Erebus has a lava lake that continuously experiences Strombolian eruptions in which large gas bubbles bursts at the surface of the lake throwing lava as far into the air. Czoski deployed six infrasound (sound that is below the human realm of hearing... less then 20 Hertz) microphones in a 30 m radius, spoke-wheel like pattern to better characterize signals coming from different sources on Mt. Erebus. While there are already some permanent infrasound sensors on Mt. Erebus, this array with its small aperture and geometry, will allow Czoski to differentiate signals much more accurately to determine the different sources. Czoski anticipates being able to identify and locate eruptions from the lava lake, ash eruptions out of another vent, rock falls from the crater rim, and perhaps ice quakes from glaciers breaking.
